DETAILED DESCRIPTION

The present disclosure provides a controller of simplified design with pivotable clamping jaws for producing higher clamping forces.

In the scope of this application, the terms “piece good” and “medicinal package” will be used, wherein these terms will also be understood to include the respective plurals. The controller according to the disclosure may be used to store and retrieve a piece good or medicinal package, or a plurality of piece goods or medicinal packages simultaneously.

A controller for a commissioning device with horizontal storage areas for storing piece goods, in particular medicinal packages, may include a delivery table with a storage and retrieval side for moving piece goods or medicinal packages from or to a storage area, the table extending in a first horizontal direction (x). The above first horizontal direction corresponds to the storage and retrieval direction for piece goods and is normally identical to the longitudinal axis of the controller. Two elongated clamping jaws are disposed above the delivery table, the jaws having clamping surfaces facing one another.

The controller may further include a clamping jaw guide apparatus with a frame structure and at least one first and one second guide which are in parallel with one another separated at a distance in the first horizontal direction (x), extending in a second horizontal direction (y) perpendicular to the first horizontal direction (x). The second horizontal direction is thus perpendicular and orthogonal to the storage and retrieval direction.

The controller itself is disposed on the side of the delivery table opposite the storage and retrieval side thereof. The first guide is defined here as the guide facing the storage and retrieval side. The second guide is disposed parallel and behind the first guide relative to the storage and retrieval side.

The clamping jaw guide apparatus may further include at least four clamping jaw carriages which are coupled to the guides and driven in the second horizontal direction (y) and movable at the guides, wherein two first clamping jaw carriages are associated with the first guide and two second clamping jaw carriages are associated with the second guide, and wherein at least two clamping jaw carriages are coupled to a respective clamping jaw at a distance from one another in the first horizontal direction (x).

The controller may also include a drive unit for moving the clamping jaw guide unit in the first horizontal direction (x), the drive unit being coupled to the clamping jaw guide apparatus.

Therefore, each clamping jaw is coupled to a plurality of clamping jaw carriages, usually to half of the clamping jaw carriages present. The coupling points are offset relative to the first horizontal direction (x) (e.g., the storage and retrieval direction) so that, for example, the motion of the first clamping jaw carriages toward one another in the second horizontal direction (y) effects a tilting of the clamping jaws together when the second clamping jaw carriages are positionally fixed.

In the controller, the control of the clamping jaws is executed very simply and directly by way of the at least four clamping jaw carriages, and no movement of a guide unit in the storage or retrieval direction is required to pivot the tilting jaws opposite to this storage and retrieval direction. Through this direct control using at least two clamping jaw carriages per clamping jaw, higher clamping forces may be applied. For example, the controller may have the at least two clamping jaw carriages per clamping jaw act in concert (e.g., by moving the two clamping jaw carriages toward one another relative to the second horizontal direction (y)). Seen from a design perspective, the controller according to the disclosure is much simpler, and higher clamping forces may be applied despite this simpler design.

In order to move the clamping jaw carriages in the second horizontal direction (y) at the guides, each clamping jaw carriage may be provided with a dedicated drive unit, for example, the drive unit sitting directly on the clamping jaw carriage. In this way, the at least four clamping jaw carriages may be moved at the guides independently of one another so that the clamping jaws may be tilted arbitrarily open and closed, whereby the two jaws tilt independently of one another.

The example of disposing a dedicated drive on each clamping jaw carriage does, however, come with greater expenses, and higher cabling and control requirements. In one or more embodiments of the controller, the clamping jaw guide apparatus includes at least two drive elements coupled to a drive unit. Here, a first drive element is connected to the first clamping jaw carriage and a second drive element is connected to the second clamping jaw carriage so that the first and the second drive elements are disposed at a distance from one another in the first horizontal direction (x). Thus, the clamping jaw carriages associated with a guide may be moved or driven through the use of a single drive element, thereby obviating the need for assigning a single drive to each clamping jaw carriage. The drive elements and the associated drive unit may be disposed in any way as long as linear motion of the clamping jaw carriages is assured in the second horizontal direction at or on the guides. To drive or move the clamping jaw carriages, any kind of linear drive can be used. For example, the drive elements may be belt-driven, the belts being redirected at pulleys at the guides and driving the clamping jaw carriages (e.g., by way of a coupling to the drive unit). In such an example, the clamping jaw carriages are designed to include appropriate coupling to the drive unit.

In order to achieve separate controllability of all clamping jaw carriages, in one or more embodiments of the controller the clamping jaw guide apparatus includes at least four drive elements coupled to a drive unit. Here, two first drive elements are connected to the first clamping jaw carriage and two second drive elements are connected to the second clamping jaw carriage, wherein the first and the second drive elements are disposed at a distance from one another in the first horizontal direction (x). Thus, only one (central) drive unit is provided, which is coupled to the clamping jaw carriages by way of the drive elements and which moves the clamping jaw carriages by way of the drive elements at the guides. The drive unit itself may include only one drive, which may then be coupled to the drive elements by way of a corresponding transmission unit in order to move the elements individually and/or in pairs.

The drive elements and the associated drive unit may be disposed in any way as long as linear motion of the clamping jaw carriages is assured in the second horizontal direction (y) at or on the guides. Thus, to drive or move the clamping jaw carriages, any kind of linear drive may be used. In one or more embodiments, the drive elements are designed as toothed racks and coupled to the drive unit accordingly. Another advantage of the toothed racks is that high forces can be transferred to the clamping jaw carriages thereby.

To retrieve piece goods or medicinal packages from storage areas, it is common to align the clamping jaws in parallel and then move the same into the storage area so that after the clamping jaws are moved inward the piece goods to be retrieved are positioned therebetween. In order to grasp the piece goods, the clamping jaws are then tilted in such a way that the ends of the clamping jaws moved into the storage areas are moved toward one another. During retrieval, the ends of the clamping jaws may abut against the sides of the piece goods, or the clamping jaws may be moved together far enough that the distance between the ends of the clamping jaws is less than the width of the rear piece good to be retrieved.

Due to the manner in which the piece goods are retrieved, the clamping jaws don't need to be moved away from one another separately. Here, a synchronous, mirror-imaged, identical motion of the clamping jaws is sufficient. Therefore, in one or more embodiments, the drive unit includes at least two drives, each having one drive gear, and the first and second drive elements designed as toothed racks are disposed opposite one another. Thus, one drive gear is disposed centrally between the first and second drive elements, respectively, so that the clamping jaw carriages associated with a guide are driven synchronously.

As discussed above, the clamping jaws move inward into the storage area in order to retrieve piece goods or medicinal packages. Since the clamping jaws are coupled to the clamping jaw guide apparatus, the apparatus is movable in the storage and retrieval direction (e.g., corresponding to the first horizontal direction (x)), which is why the clamping jaw guide apparatus is coupled to a corresponding drive unit.

In order to provide a controller with as large of an open delivery table area as possible (e.g., with as compact a clamping jaw guide apparatus as possible), in one or more embodiments a component of the frame structure of the clamping jaw guide apparatus reaches around the delivery table and is coupled to a drive unit disposed below the delivery table, the drive unit moving the clamping jaw guide apparatus. In such an embodiment of the clamping jaw guide apparatus, it is possible to dispose the drive for moving the clamping jaw guide apparatus in the storage and retrieval direction below the delivery table such that the clamping jaw guide apparatus is designed very compactly relative to the first horizontal direction (x).

In one or more embodiments, the drive unit for moving the clamping jaw guide apparatus is designed as a linear drive with moving parts and stationary parts. Here, the moving parts are coupled to the component of the frame structure that reaches around the delivery table and the stationary parts are designed below the delivery table.

To move piece goods or medicinal packages placed on the delivery table from the same to a storage area, the controller may include a pusher (e.g., a telescope arm), wherein the pusher may be coupled to the clamping jaw guide apparatus or may be designed as a component of the clamping jaw guide apparatus.

In order to keep the design of the clamping jaw guide apparatus as simple as possible, one or more embodiments provide that the delivery table has an opening extending in the first horizontal direction, a pusher being movable in the opening in the first horizontal direction, wherein the pusher is coupled to a drive. The mechanism for moving the pusher is therefore disposed primarily below the delivery table so that the number of components of the clamping jaw guide apparatus is reduced.

In order to avoid slippage of clamping jaws against piece goods as they are retrieved, in one or more embodiments at least one section of the clamping surfaces of the clamping jaws includes a non-slip material. For example, either the jaw is made of such a non-slip material or the jaw is coated, at least in sections, with a non-slip material.

FIGS. 1a, 1b show two perspective views of one or more embodiments of the controller, wherein FIG. 1a reflects a perspective view from above and FIG. 1b reflects a perspective view from below. The controller 1 includes a delivery table 10, above which two clamping jaws 20 a, 20 b having opposing clamping surfaces 21 a, 21 b are disposed. The free ends of the clamping jaws 20 a, 20 b may have a section 22 a, 22 b that is coated with a non-slip material.

At the free ends of the clamping jaws 20 a, 20 b, the delivery table 10 has a storage and retrieval side 15 past which medicinal packages are pushed from the delivery table 10 onto storage areas or pulled from the storage areas onto the delivery table 10. The storage and retrieval direction corresponds to the first horizontal direction x indicated in FIG. 1 a.

The delivery table 10 has a central slotted opening 11 that extends in the storage and retrieval direction (e.g., in the first horizontal direction x). A pusher element 12 with a broadened pushing head 13 is disposed in the opening 11. The pusher element 12 may be moved in the slotted opening 11 in the storage and retrieval direction (e.g., in the first horizontal direction x).

A clamping jaw guide apparatus 30 is disposed opposite to the storage and retrieval side 15, with clamping jaws 20 a, 20 b being connected to the clamping jaw guide apparatus 30. The clamping jaw guide apparatus 30 may include the mechanism for tilting the clamping jaws 20 a, 20 b. In the upper section, the clamping jaw guide apparatus 30 includes a clamping jaw drive unit 50 with first and second drives 51, 52, as well as associated first and second transmissions 53, 54. As shown, the first and second drives 51, 52 cause the clamping jaws 20 a, 20 b to tilt in a manner described in detail in the subsequent figures. The clamping jaw guide apparatus 30 may also include an optical detector 2 for monitoring various aspects of the storage and retrieval process.

The clamping jaw guide apparatus 30 and all the electronic components thereof are connected to a control unit 4 that is disposed below a fastening arm 3 as shown. The fastening arm 3 may be fastened to the delivery table 10 or to a substructure thereof by way of a swivel joint 5.

To store and retrieve medicinal packages, the clamping jaw guide apparatus 30 is moved in the first horizontal direction x (e.g., the storage and retrieval direction). To this end, a guide apparatus drive unit 60 may be disposed below the delivery table 10, the guide apparatus drive unit 60 moving the clamping jaw guide apparatus 30 as described in the subsequent figures in detail. Further disposed below the delivery table 10 may be a pusher drive unit 6 for moving the pusher element 12 in the first horizontal direction x in the slotted opening 11.

FIGS. 2a and 2b are perspective views of the clamping jaw guide apparatus 30 together with the clamping jaws 20 a, 20 b. The clamping jaw guide apparatus 30 includes a frame structure 37, the frame structure 37 having a front component 31, a top component 32, and opposing lateral components 33 a, 33 b. The front component 31 may be configured to reach around the clamping jaws 20 a, 20 b and the delivery table 10 (see FIGS. 1a, 1b ). Fastened at the lower ends of component 31 are moving parts 62 a, 62 b (e.g., the “runners”) of a linear drive, the runners being able to move the clamping jaw guide apparatus 30 in the first horizontal direction. The components are called “moving” components since they move in the first horizontal direction together with the clamping jaw guide apparatus 30 along corresponding stationary parts, which are rotated so as to move the moving parts. The stationary parts 61 a, 61 b (see FIG. 1b ) themselves may move in order to move the moving parts, for example by rotation of the stationary parts, whereby this rotational motion may move the moving parts along the longitudinal axis of the stationary parts. The stationary parts are therefore only themselves stationary relative to the positions thereof within the controller 1.

For example, the stationary parts may be provided as belts designed between the longitudinal ends of the controller 1 and that cooperate with corresponding pulleys for moving the moving parts.

As can be seen in FIGS. 2b and 3, a first guide 35 and a second guide 36, extend parallel to one another between lateral components 33 a, 33 b in a second horizontal direction y. Here, the guides 35, 36 are separate from one another in the first horizontal direction x, wherein the first guide 35 faces the free ends of the clamping jaws 20 a, 20 b.

Clamping jaw carriages 40 a, 40 b; 41 a, 41 b are disposed at each of the guides 35, 36. Two first clamping jaw carriages 40 a, 40 b may be disposed at the first guide 35 and two second clamping jaw carriages 41 a, 41 b may be disposed at the second guide 36. A section of the clamping jaw carriages 40 a, 40 b; 41 a, 41 b may reach around a projecting end of the guides 35, 36 such that part of the clamping jaw carriages 40 a, 40 b; 41 a, 41 b sit on the projecting end.

In one or more embodiments, the guides 35, 36 and carriages 40 a,40 b; 41 a, 41 b may be designed in slightly different ways. For example, the guides 35, 36 may be designed as simple tubes through which surrounding clamping jaw carriages 40 a, 40 b; 41 a, 41 b may be moved. The exact design of the guides 35, 36 and the clamping jaw carriages 40 a, 40 b; 41 a, 41 b is insignificant for the present disclosure. It is only important to ensure that the clamping jaws 20 a, 20 b may move parallel to one another and in the second horizontal direction y, which runs perpendicular and orthogonal to the first horizontal direction x.

As can be seen in FIG. 3 in particular, the clamping jaw carriages 40 a, 40 b; 41 a, 41 b are connected to drive elements 45 a, 45 b; 46 a, 46 b, which may be designed as toothed racks as shown. The drive elements 45 a, 45 b associated with the first guide 35 and the corresponding first clamping jaw carriages 40 a, 40 b, and the corresponding drive elements 46 a, 46 b associated with the second guide 36, may be aligned relative to the tooth elements of the racks in such a way that the tooth elements oppose one another and form an overlapping area at the free ends thereof. Disposed in the center of the overlapping area of the respective drive elements or racks 45 a, 45 b; 46 a, 46 b are first and second drive gears 55, 56 that are coupled to first and second drives 51, 52 by way of first and second transmissions 53, 54 (see FIG. 1).

The distance between the clamping jaw carriages 40 a, 40 b; 41 a, 41 b of a guide 35, 36 and the corresponding drive gear thereof may be identical. In other words, a drive gear may be disposed precisely in the center between two clamping jaw carriages 40 a, 40 b; 41 a, 41 b so that a movement of the drive gear causes synchronous movements of the clamping jaw carriages 40 a, 40 b; 41 a, 41 b. When the drive gear is rotated, the clamping jaw carriages 40 a, 40 b; 41 a, 41 b are moved synchronously toward or away from one another, wherein the same applies to the clamping jaw carriages 40 a, 40 b; 41 a, 41 b associated with the two guides 35, 36.

The clamping jaw carriages 40 a, 40 b of the first guide 35 may therefore be moved simultaneously or separately with respect to the clamping jaw carriages 41 a, 41 b of the second guide 36, providing a large degree of flexibility with regard to movement of the clamping jaw carriages 40 a, 40 b; 41 a, 41 b. The clamping jaw carriages 40 a, 40 b; 41 a, 41 b of the first and second guides 35, 36 may be moved synchronously or only the clamping jaw carriages 40 a, 40 b; 41 a, 41 b associated with either the first or the second guide 35, 36 may be moved. In this way, it is possible to move the clamping jaws 20 a, 20 b that are fastened to the clamping jaw carriages 40 a, 40 b; 41 a, 41 b, in parallel or already tilted, simultaneously without any change in angle (e.g., by simultaneously moving the clamping jaw carriages 40 a, 40 b; 41 a, 41 b of both guides 35, 36). If it is only the clamping jaw carriages 40 a, 40 b; 41 a, 41 b of one guide 35, 36 that are to be moved, it is possible to tilt the clamping jaws 20 a, 20 b.

In one or more embodiments, one drive element 45 a, 45 b; 46 a, 46 b is associated with each clamping jaw carriage 40 a, 40 b; 41 a, 41 b. In one or more embodiments, only two drive elements may be provided, wherein the two drive elements are associated with one guide and are designed as belts for driving the clamping jaw carriages 40 a, 40 b; 41 a, 41 b, for example. In one or more embodiments, pulleys may also be provided for the belts. The pulleys may be coupled to the guides 35, 36 or to the frame structure 37. Further, a coupling between the clamping jaw drive unit 50 and the drive elements/belts may be provided.

As explained above, clamping jaws 20 a, 20 b are coupled to the clamping jaw guide apparatus 30. This coupling can be seen in FIG. 2b . Here, clamping jaws 20 a, 20 b may be connected to clamping jaw carriages 40 a, 40 b by way of a respective swivel joint 23 a, 43 a; 23 b, 43 b of the first guide 35 and to clamping jaw carriages 41 a, 41 b of the second guide 36 by way of a slotted hole guide 24 a, 25 a, 44 a; 24 b, 25 b, 44 b. In one or more embodiments, the swivel joint may be disposed at the clamping jaw carriages 41 a, 41 b associated with the second guide 36. In this case, the slotted hole guides 24 a, 25 a, 44 a; 24 b, 25 b, 44 b may be disposed at the clamping jaw carriages 40 a, 40 b associated with the first guide 35.

However, it is not absolutely necessary to use the swivel joint/slotted hole guide combination. The clamping jaws 20 a, 20 b are held using a swivel or pivot joint at the corresponding clamping jaw carriages 40 a, 40 b; 41 a, 41 b of at least one guide, but use of a slotted hole guide is not absolutely required. Thus, for example, in one or more embodiments, the clamping jaws 20 a, 20 b may be moved together with the clamping jaw carriages 40 a, 40 b; 41 a, 41 b against a restoring force, and when the clamping jaw carriages 40 a, 40 b; 41 a, 41 b are moved back the restoring force moves the clamping jaws 20 a, 20 b back.

FIGS. 4a, 4b show a top view and bottom view of the clamping jaw guide apparatus 30 with the clamping jaws 20 a, 20 b tilted, wherein parts of the frame structure 37 and the clamping jaw drive unit 50 are left out. In FIG. 4a , it is easily seen that the first and second drive gears 55, 56 are disposed exactly in the center between corresponding clamping jaw carriages 40 a, 40 b; 41 a, 41 b so that a rotating motion of the first and second drive gears 55, 56 effects a synchronous movement of the associated clamping jaw carriages 40 a, 40 b; 41 a, 41 b.

FIG. 4b shows a detailed view of the swivel joints 23 a, 43 a; 23 b, 43 b and the slotted hole guides 24 a, 25 a, 44 a; 24 b, 25 b, 44 b. Pins or projections 43 a, 43 b, 44 a, 44 b of the swivel joints and slotted hole guides 24 a, 25 a, 44 a; 24 b, 25 b, 44 b are provided by the corresponding clamping jaw carriages 40 a, 40 b; 41 a, 41 b, whereas the corresponding receptacles are provided by the clamping jaws 20 a, 20 b or by components disposed thereon.

FIG. 5 shows a detail view of the clamping jaw guide apparatus 30, wherein parts of the clamping jaw drive unit 50 and of the frame structure 37 are left out to provide a better view of the remaining components. In FIG. 5, clamping jaws 20 a, 20 b have been brought together and are aligned parallel with one another. In a comparison of FIGS. 3 and 5, it can be seen how the position of the clamping jaws 20 a, 20 b is influenced by a shift of the clamping jaw carriages 40 a, 40 b; 41 a, 41 b at the guides 35, 36.

FIGS. 6a, 6b show a top view and a bottom view according to FIG. 5 (e.g., of a clamping jaw guide apparatus 30 with parallel clamping jaws 20 a, 20 b brought together). In FIG. 6b , it can be seen that the projections or pins 44 a, 44 b of the clamping jaw carriages 41 a, 41 b of guide 36 are disposed in slotted holes 25 a, 25 b entirely “at the bottom” since the clamping jaws 20 a, 20 b are situated parallel. Thereby, the section of the clamping jaws 20 a, 20 b located between the first and second guides 35, 36 is the smallest. When the clamping jaws 20 a, 20 b are tilted, whether inward or outward relative to the ends of the clamping jaws 20 a, 20 b, the section of the clamping jaws 20 a, 20 b (e.g., the length thereof) located between the guides 35, 36 increases such that the projections or pins 44 a, 44 b would travel “upward” within slotted holes 25 a, 25 b. In one or more embodiments, it may not be required for the “slotted hole” as such to be closed, but instead an open slotted hole (e.g., a type of fork) may also be used for guiding the pins or projections.
